Watch: Man threatens to stab cyclist, chases him down on Auckland bike path

A cyclist has described being followed by a "thug" along a bike path in Tāmaki Makaurau/Auckland on Friday, with a video to prove it.

The cyclist, who Newshub has agreed not to name, was biking along the Grafton Gully Cycleway just before 11am.

"I was going uphill, towards the next part of the ride. I heard a kind of heckling, hyena-like laughing. And then I saw the guy's head over the hedge," the cyclist told Newshub.

"He started heckling and laughing, and I said 'f**k off' and carried on my way."

The man then yelled back "I'll f**king stab you".

The cyclist continued on the uphill section, near Upper Queen St, without realising he was being followed.

It turns out the man had been running after the cyclist for about 40 seconds before the cyclist realised.

"I turned around and saw him behind me. I just gapped it. I didn't realise he was on my tail," he told Newshub.

"If it wasn't for him shouting, I don't know if I would've gotten stabbed or mugged."

And it appears it wasn't the only incident in the area that morning.

A police spokesperson confirmed to Newshub there was a report of an assault on the bike path earlier that Friday.

"We've received a report of an incident where a cyclist was assaulted on the Grafton Gully Cycleway," they said.

"Police carried out an area search, however the suspect wasn’t located."

The Grafton Gully Cycleway opened in 2014.
